I just started getting this error for only a couple of my workbooks on Tableau Public.

any resolution yet?

My workbooks and visuals were working great a few weeks ago. When I went to view my viz online in Tableau Public in my web browser, it threw an error saying to contact my Tableau Server administrator but we do not have Tableau Server. we use Tableau Public exclusively.

I then tried to open my workbook via Tableau Public Desktop and it opens and operates just fine, no problem with the data source nor any functionality. But when I try to save any changes back to Tableau Public I get the same Tableau Public error message as Tony Covey. This renders the file and all the work done on it as useless.

It appears the problem is tied to the use of the Group feature. When I delete the groups the VIZ publishes without issue. As a workaround I added a column to my data and assigned groups within Excel itself. Fortunately, I'm working with an extremely small dataset so it wasn't a huge deal for me, but I'm guessing that in most cases this is far from the ideal solution.
